Ethiopian Airlines crash: Crew complied with emergency procedures, preliminary report finds

Black boxes from Ethiopia crash to go to Europe for analysis

UAE to validate any Boeing MAX fix before lifting airspace ban

On Thursday, Boeing spokesman Peter Pedraza said: "Boeing will be reviewing the published report as it is released".

It said air speed and altitude values on the left side of the 737 Max conflicted with data from the right sensor, causing flight control problems.

The airline's group chief executive Tewolde GebreMariam said everyone at Ethiopian Airlines "are still going through deep mourning" and expressed "deep sympathy and condolences for the families' relatives and friends of the victims".

This pushed the jet downwards because the plane thought the engines were about to stal.

However, Muilenburg recognized that "erroneous activation" of a so-called Maneuvering Characteristics Augmentation System created to prevent stalls had occurred.

Investigators are looking into the role of the Maneuvering Characteristics Augmentation System, a flight control system known by its acronym, MCAS, which under some situations can automatically lower the plane's nose to prevent a stall.

But a fix to the Boeing 737 Max will have to win the confidence of not only the FAA, which regulates the plane, but also of the local aviation authorities who have grounded the aircraft model and banned it flying over their airspace, he said.

Last week, Boeing announces it was testing a software update to the software said to be to blame for the accidents.

The report recommends "the aircraft flight control system shall be reviewed by the manufacturer", she said.

While the USA manufacturer and aviation regulators made a point of telling airlines worldwide how to disarm MCAS, the pilots of the Ethiopian Airlines plane were found to have followed "all the procedures repeatedly", according to Dagmawit.

Since that initial Lion Air crash, the FAA and Boeing have released instructions on how to deactivate this component of the autopilot and recover control of the aircraft. Flight crews will always have the ability to override MCAS and manually control the airplane.

But the latest comments from Ethiopian officials suggest that pilots could not regain control, despite following procedures recommended by Boeing.

Boeing said it would study the report.

Preliminary findings of an investigation into the crash are due to be released this morning by officials in Ethiopia. "It is so sad to learn that our loved ones would have been spared if this problem was detected on time". I heard the full report may take one year.

Africa's only consistently profitable carrier, Ethiopian has built Addis Ababa into a major hub feeding travelers from around the world into dozens of African cities in competition with rivals such as Dubai-based Emirates. Boeing was close to a software fix when the Ethiopian Airlines jet went down. The complaint, which also names Ethiopian Airlines and parts maker Rosemount Aerospace as defendants, is alleging negligence and civil conspiracy, among other charges.

Stumo, originally from MA, is the niece of consumer activist Ralph Nader, who called for a boycott of the 737 MAX on Thursday.

Boeing has since stopped deliveries of the 737 Max, and has mandated a previously optional cockpit warning light, but maintains their new fuel-efficient aircraft is safe.

China said it's been invited by the FAA to join a panel to review the 737 Max. Anonymous sources inside the FAA told the Times that the agency inappropriately delegated the airplane's certification to Boeing employees.

Boeing also is continuing to work closely with the U.S. National Transportation Safety Board (NTSB) as technical advisors in support of the AIB investigation.

Boeing on Thursday said it would take "any and all" necessary safety measures to ensure the airworthiness of its jets following last month's deadly crash in Ethiopia +.

The Senate panel's probe is the latest in a string of investigations by United States officials and lawmakers into how the FAA cleared the 737 Max as safe to fly.
